a month after错了吗？

       高考题也有出现失误的情况，所出的题有时有错误或出现不当，我收集了部分错误高考题，并进行详细的分析，目的是为了不让这些错误的高考题继续“误人子弟”，因为人们视高考题为权威，不敢怀疑，即使觉得不对劲，也坚信它的“正确性”，有些老师甚至将这些错误的或“有问题”的高考题当做权威试题继续拿来考学生，可见其“危害性”该有多大！

When I was in high school, most of my friend had bicycles. I hoped I could also have it. One day I saw a second-hand bicycle, that was only one hundred yuan. I asked my father the money.  But he said he could only give me half of the money. He should find the other half myself. So I went to sell newspapers after the school. My father was pleased if I showed him the money a month  after. He gives me the other fifty. You can imagine how much happy I was when I rode to school on  my own bicycle.

这是2009年辽宁高考英语短文改错题，第8个“错误”所给的正确答案是将a month after改为a month later。实际上，a month later完全正确！

分析：

after常用作连词或者介词，但是，除此之外，它还可用作副词，表示（过去时间里的）若干时间之后。也就是说，此题中a month after=a month later！a month after完全正确！根本就不错！
